Default tips on installing WP d/s seal?

any tips on installing the water pump drive shaft seal? I pressed the 1st one into the timing chain cover and then installed the cover..and screwed up the first seal I had. a new one arrived today and the timing cover is on but I'm afraid of messing it up again, it sure is a tight fit. any tips? should I install the seal on the drive shaft 1st or the timing cover or does it not matter?

I just used a chunk of wood and an arbor press, didn't really put much thought into it just make sure it is square in the bore before you press it inot the cover.

which side of the seal should I push the drive shaft through? the front with the yellow band or the rear with the gray rubber? the d/s is slightly bigger than the seal...I really don't see how I am going to do this with out ruining the seal again, should of just left the old one I guess but now I have to, I'll put oil on it again but it didn't help much last time. anyone have any tips please? it takes 3 days to get another seal if I screw this up again..

got this tip off google if anyone is ever wondering the same thing>
"You'll need to cut a 1"x 2" piece of plastic from a 2 liter soda bottle. Wrap that around the water pump drive shaft before you try to install the seal. Once you wrap the plastic around the shaft, make it a little narrower on the open end put a drop or two of oil on the plastic, now gently slide the seal over the plastic/drive shaft. Seat the seal as you would with an appropriate socket. One the seal is seated, grab the plastic with a pair of needle nose pliers and carefully pull the plastic sleeve straight out. This little trick will keep you from trashing the seal during the install."
